' Specification forming-part of. Letters Patent No.' 7 3',93s,jdated January 28, 1868.

To all whom it may concerni v Be it known that I, Louis STRAUs ofLouisville, in the county of J efl'e rson-an State of Kentucky, have invented a new and Improved Modeof Cleaning Privy-Vaults and cisterns" containing putrid matters; and I do hereby.

declare that 'the following is a full, clear, and

exact description the'r eofijreferencev being had -to the accompanyingdrawings, making a part of this specif cation, in which- Figure 'l'is a perspective view of the innproved apparatus usediii cleaning privy and. other vaults. Fig. 2"is atop. view, showing the pump-cylinder in horizontal section.

Similar letters of reference indicate corre sponding parts in the twovfi'gures.

This invention consists .in a new and improved mode of emptyin privywaults? and other reservoirs containing putrid manorious matters, whereby the work can be done with great facility.

The invention consists, further, in the chiployment of a portable air-tight reservoir or receiver'for containing thematters removed" from the vaults, and agas-bnrning stove for consum ng the gases arising from .said'matters while conducting them into the receiver.

The invention further consists in the com-- hination', with the second feature of inventron, as ust stated, of a forcingengine, and

suitable connecting pipesor hose,for pumping the matters from the vaults into therecciver, as will be hereinafter described. 'Itv also consists in providing for keeping the enginc-ports clear and free from solid substances, by constructing-the valves or cut-offs of the piston-cylinder so that they shall act as cuttors and clearers, as will be hereinafter described. v 'lo cnableothers skilled in the art to understand'my invention, I will describe its construction and operation. 1

, In the accompanying drawings, A repre; sents an air-tight tank orv reservoir-ywhieh may be constructed in any suitable manner,

and which is provided with an opening covered with glass, so as to expose the interior, and allow a person to see 'when it'is filled. Clhistank is also provided with pipe-connections 0. a,'and with a draw-off nozzle, 0., To

the connection a a hose is attached, which theair and gas from tank A- during the proce'ss of filling it; TheQ'gas-burner Bmay beconstru'c'ted, in" anysn'itable manner,- for burn- ..ingcha-rcoa-l or other deodorizer for purifying the escaping gas. ,To the connection a. the pipe: or hose'C is applied, which leads off to the puin pin g-engilie, and jsvsuitably connected to the couplinggpipe c. The cylinder D of the engine may be constructed like the well-known double-actingpu-mp cylind'ersv It is provided with. a solid :pistOn, E, the -piston-rod' E of" inner edge of which is beveled and brought toa knife-edge, as shown in Fig. 2, These valves are connected together in pairs by-meansof the reciprocating frames G -Gr, placed on the sides of the cylinder D, as shown. To the valve-frames G'G' rods J J are attached, and onthe ends of these rods slotted boxesK K,-

.through which the crank-shaft F passes. Wit-hin these boxes,and keyed upon the crankshaft, are cams or toes m m, so arranged as to operate alternately upon the ends of the boxes K K, and communicate an alternate reciprocating movement to the valve-frames. By this arrangement and operation of the parts the, pump Will operate upon .the principle of a double-acting forcing-pump; 01 ,111:

other'words, whenlthe piston'is moving in one direction, one valve will be open to allow the liquid matter to rush in behind the piston, and

"lanothervalve will be open to alhow'thc piston to'forcethe matter to rush out beforeit.

When the piston ret'urns,.the same. operation will take placeby the opening of the opposite valves.

To vthe coupling-pipe 6, leading to "the induction-valves, a hose-pipe is to be attached, which is carried ofi'to the vault to beemptied, and, if desirable, provided on its. end with a 2. 1 v mass rose-nozzle, to prevent substances from being drawn into the hose which would :be lia'ble to 'elogit, k i

In practice, it will be found best to have the sliding valves app lied so as to work as near as possible to the interior ends of the' ports,"so from clogging, by,

as to prevent the latter eausin g these valves to out their-way through any solid substances which might lodgel'n the ports.

I11 practicepthe apparatus which I; have above described will be suitably mountcdnpon a carriageiso that it can be conveniently transported fro n'one place to another. I do not confine my invention to the precise constructioii of the several parts herein described, as these parts may be modified without changing their prinoipleof operation. Itwill be found advantageous to have the pipe-connections uponthe several parts of the apparatus provided with screw orothersuit- ,i able caps, so that when the hose-pipes are re moved suohcaps may be applied to said coni nections, so as to prevent the escape ot-iou gases. I f Having described one practical mode of carrying out my invention, what I clann as new and desire to secure by LettersPatent, is

1 The combination of the reservoir or receiving-tai'ik Aand deodorizer 1'3 with a forcing-engine,substantiallyasand for the purposes described.

2. The sliding valves Z of the engine, con- 'st -ruoted .with cutting-edges, substantially in themannerand for the purposes described.-

An apparatus for emptying privy-vaults, constructed and operating substantially as described.
